Hi Team,
I am new to winform development.
I have bound the RadDropdownList with values from database with DisplayMember and ValueMember properties set properly.
I can see the items in dropdown with no problem.
But when I want to assign the value to RadDropdownList, it sets always to 0 (zero).

Please take a look at my code to bind dropdown :

public void FillInvoiceTypeCombo(int EventTypeID)

{

object businessObject = null;

if (EventTypeID == GlobalConstants.ACCOUNTJOURNAL_EVENT_TYPE_ID_FOR_AP_INVOICE)

businessObject = VoucherDocumentTypeNameValue.GetVoucherTypeNameValue(GlobalConstants.ACCOUNTJOURNAL_EVENT_TYPE_ID_FOR_AP_INVOICE);

else

businessObject = VoucherDocumentTypeNameValue.GetVoucherTypeNameValue(GlobalConstants.ACCOUNTJOURNAL_EVENT_TYPE_ID_FOR_PO_WO_SERVICING);

cmbInvoiceType.DataSource = (VoucherDocumentTypeNameValue)businessObject;

cmbInvoiceType.DisplayMember = "Value";

cmbInvoiceType.ValueMember = "Key";

}

And in another method, I am setting the value of dropdown :

pub void SetControls()

{

// Fill DataSet ds with values from db

FillInvoiceTypeCombo(int.Parse(ds.Tables[0].Rows[0]["AccountJournalEventTypeID"].ToString()));

cmbInvoiceType.SelectedValue = int.Parse(ds.Tables[0].Rows[0]["InvoiceTypeID"].ToString());

}

But every time I get SelectedValue as 0 (zero).

Can you please tell me how can I set the value of the RadDropdownList?

Exceptions in a recurrence rule

I was wondering how exactly exceptions are stored. In the master event's recurrence rule?

For example, if I had deleted an occurrence of a recurring appointment, how would that be stored in a database? Maybe something like DELETEDDATES=ddMMyyyy in the recurrence rule?

Thanks!

Why CurrentRowChanged fires twice?

Hi everybody.

I have a problem with CurrentRowChanged event of GridView. My problem is next.

At form's load event I do this: (rgvClientes is the GridView)

this.rgvClientes.CurrentRow = null;
this.rgvClientes.CurrentRowChanged += new CurrentRowChangedEventHandler(this.rgvClientes_CurrentRowChanged);

And when I click on a Row from the GridView the event CurrentRowChanged fires twice but only the first time, after that it fires only ojne time when a click on a different row.

Someone can explaine me this issue?

Can't Sort Days Order of Appoinments in Monthview

Hello,

I use RadScheduler in my project and my appointments have custom colors, icons etc.

I add appointments to RadScheduler manually in the following way:

foreach (var app in appointments)

radScheduler1.Appointments.Add(app);

I have a problem with RadScheduler MonthView. I want to add appointments to MonthView and I want them to be shown sorted by time (IEvent.Start.TimeOfDay), so if app1.Start.TimeOfDay > app2.Start.TimeOfDay and app1.Start.Date == app2.Start.Date then app1 should appear under app2.

I tried to solve this problem by ordering my appointments collection:

var appointments = src.OrderBy(a => a.Start.TimeOfDay);

foreach (var app in appointments)

radScheduler1.Appointments.Add(app);

But this did not help, so is there a way to solve this problem? Actually I need a way for sorting appointments by time in MonthView.

I am sending you an image of the MonthView, where you can see that appointments are ordered in an inccorrect way. Take a look at Dec 20 and you will see the appointment, that appears at the bottom has its Start.TimeOfDay 09:15, so it should appear as the second starting from the top. Why does it behave in such a strange way?

Thank you for your support.

Expression Based Conditional Formatting on Child Rows

Hi,

I have conditional formatting rules on a parent grid that are defined as expression types

New ExpressionFormattingObject ("COL1",Expression:="COL2 = 1", etc.)

The compare data is in a different column than the formatting. This works OK for the Grid.MasterTemplate.Columns.

I also have identical rules defined for Grid.MasterTemplate.Templates(0).Columns, however the styling does not get applied for these rows on the child grid. If I change the child rules to be ConditionalFormattingObject type as:

New ConditionalFormattingObject ("COL1", Equals, Value:="1", etc.)

the styles are applied correctly. I can't do this though as the data item is in a different column than the formatting. (test against COL1, style COL2)

Is there something I need to do to get the expression rules to format correctly?

Many thanks,

Mark.

RadProgress bar fails to update.

I'm not understanding why it fails to update in another thread correctly if the process is running fast. Example

If I do this, this will freeze the progress bar until its completed. It will get to a certain spot then stop.

radProgressBar2.Maximum = 1500;

for (var i = 1; i < 1500; i++)

{

var p = i;

radProgressBar2.Value1 = p;

Thread.Sleep((int)numericUpDown1.Value);

}

radProgressBar2.Value1 = 0;

radProgressBar2.Text = "Task Completed!";

If i do this

radProgressBar1.Maximum = 1500;

for (var i = 1; i < 1500; i++)

{

var p = i;

radProgressBar1.SafeInvoke(() => radProgressBar1.Value1 = p, false);

Thread.Sleep((int) numericUpDown1.Value);

}

using a custom invoke it works just fine. I dont understand why it doesnt work correctly with the build in feature. This is also happening on the status progress bar as well.. Here is a quick app source.

Also it seems to work with the built in features using Win7 or above, Its freezing on windows xp sp3

Edit: Never mind i can not attach rar, or .zip to this thread.

Uploading a video to demonstrate.
